GAE-ROOF CONSTRUCTION Specification of Letters Patent.

To all whom it 'IflQQZ/CONCQTIL.

Be it known that 1, Lane G. N iLsoN, a citizen of the United Statcs,1rcsiding at Iloboken, in the county of lludson'and State of New Jersey, have invented certain new and useful Improvements in Cardtoof Construction, of which the following is a full, clear,

and exact specification.

This invention relates to car roof construction, and has particular reference to a construction of roof wherein the strength will be,

'as mufflers, coolers and the like.

In ordinary practice, a car roof is made up of rafters and upper sets of car-lines connected by vertical deck sections carrying the upper ventilating windows. This constiaiction is satisfactory from the standpoint of ventila' tion, but is weak considering its weight, owing to the many joints where the rafters and upper carlines join theupper side of the car and the longitudinal stringers forming the deck sills and deck plates. In such cars, the interior finishing has been Znade u so as to follow the lines of the frame winl closely, While in the more ornamental cars, such as Pullman, parlor and sleeping cars, the interior finish has been changed so as to arch over between the lower deck sills and ventilating windows in the upper deck. These windows have been made half oval and.

placed farther a art than ordinarily, the smaller cross arches opposite the windows being made to join the main arch of the head lining, and producing the general effect coinnionly known as an em )ire roof. In some instances, the upper'deck carrying the ventilating windows, is dis ensed with and the oarlincs arched uniform y from one side to the other. The interior appearance of such a car is ob ectionable because of 1ts rescm blance to a tunnel, as well as the increased roof plates.

diiiicult in socuring'eifective ventilation.

The )jects of this invention are to provide a car roof construction in which the weak upper or monitor deck constructionfor the ventilating windows will be dispensed with, and instead,- the carlines arched uniformly across from side to side and carrying the Between certain of these carlines, vertical arches will be provided for the ventilating windows and the roof plates cut out somewhat in parabolic form soas to rovide ventilating windows somewhat ike dormers in the arched roof. The spaces between the window arches will be filled up preferably by gratings so as tohave the external appearance of an ordinary monitor deck railroad car, and the interior finish will be broken so as to resemble in general the empire roof. This will leave a space on the roof above the carlines and between the window'arches for carrying coolers, radiating coils, etc., and not affecting the appearance of the car. More particularly, such a constructionis intended for use in motor cars using-the internal combustion engine for ower, wherein it is desired to provide s ace fbr inufliers, water coolers, tanks, etc., w ich cannot be'conveniently carried under the car. By disposing such devices upon the roof,

there will be a free circulation of air from' above and through the gratings, as well as an abundance of space. The invention with reference to a particular form thereof, is shown in the accompanying drawings, wherein F'gure 1 is a side elevation of a motor car embodying the invention; Fig. 2 is a plan view of the car interior; Fig. 3 is a perspective view showing the external appearance of the roof; Fig. 4 is a cross section on the line 4-4 of Fig. 1; Fig. 5 is a detail, on an en larged scale, of the upper corner of the roof at the top of a ventilating window; Fig. 6 is a fragmentary perspective of the interior finish of the car; and Fig. 7 is a detail view showing the arrangement of grating for directing the current of air produced by the motion of the car over the radiating coils or other devices on the roof, which it may be desired to cool.

Referring now to Fig. 1-, 1 represents the body ofacar-having an engine compartment at the front-end separated by a double partition 2, and suitable wheels mounted on trucks. Between the double walls are blocks of rubber or other vibration absorbing material 3, to irevent the walls from acting as a sounding card. The side of the car is com oscd of uprights, prefcrabl r angles 5,

on t e outside of which the letter )oard 4 and composed of an angle securedto the upper tilating this compartment. This compartends of the u rights 5 with the u per flange turned mwar Un1formlyarche across are the carlines 10, which also are preferably coniposed of angle bars. Carried directly by the carlines 10 are the roof plates 1 1 which will be secured rigid ly'to the carlm es so as to strengthen then andproduce a rigid upper roof structure. it will be here observe that the carlines 10 are located between the uprights 5, and this 13 to enable the ventilating windows 13 to come preferably over the upper windows Sand between each pair of windows 7, as this improves the ornamental appearance oftho car and will not differ materially in appearance from cars commonly used. The upper ve lating windows 13 are carried by arches Lt, between adjacent carlines l0, and

the corresponding roof plates are out out in a somewhat parabolic form, as will appear from .l 1g. so that a curved plate or hood 15 can be fastened to the arch 14. and to the roof plate. 'lhesc hoods or curved plates can preferably be made of sta mpings and thus be vertically extending projecting vanes 22 which will project outward in order to direct a current of air into the spaces betweei'i the hoods 15. if desired, these vanes can be made to turn so as to catehthe air in whichever direction the car is moving, but ordi narily one end will he the front, and the car will usually go in this direction.

Fig. 5 shows on an enlarged scale, the ar ran gement in which the upper deck stringers 19 are carried by an angle plate 24 which is secured to the arches 14 by the inside plate 25, so that the outside resembles the appear ance of an ordinary monitor decked car, and has adequate ventilation as well as a larger spa-3e between the dock stringers for the disposition of cool ..'-i, inuil'lers, tanks, and other devices not hi .n such a weight as to make the car top heavy; 26 represents, for exam- I ple,.a cooler for the water jacket circulation of a gas engine, supported by arms 27 attached lo the roof plates and 'carlincs 10, and the outer surface area of this cooler will he proportioned according to the usual prac ticc. Also, Inulllers, tanl and other parts of the equipment can be siorcd here, as the i'mdcrbody of the car will ordinarily carry a storage battery 2U. At the front end of the car, there is an engine compartmentseparated by a. partition, and by reason of the heat. ii 1. desirable to provide means for ventop of the engine compartment.

ment extends across just back of the side be higher than the car inos and open at the This opening will be closed by a pivoted, transversely extending, ventilating door or window I30, which can be operated from the interior in any desired manner. By opening one of the front windows, the desired amount of ventilation of the engine room can be secured without any chance of causing this heated air to be driven into the interior of the ar.

The interior linish of the car may be arched uniformly across and carried by the cal-lines, but )referably this will be somcwlu'tt broken by ropping a molding 27 somewhat below the carlines and under the ventilating windows. Head linings 32, 33

mental trin'unings. Fig. 6 shows the window sills 36 under the ventilating windows dropped down, with a separate piece of head lining 37 connecting it to the interior longitudinal finishing strip 3!), which runs the length of the car above the windows. in this construction' the spaces between the ventilating windows can. be used for racks 38, as shown in Fig. 6, which gives a much increased head room for the racks over that ordinarily provided.

i It will, of course, be understood that the general finish forming the interior and extc rior can be changed in various respects without varying materially from the principles of the invention.

The invention provides a roof frame work and arrangement which is simple and prac tical to build, and'of great strength,without involving too much of a departure from recognized standards of ap )c'al'ancc.
